“...if he was a Torah observant man or rabbi...”
That is why the Pharisees hated Jesus and one of the reasons He ended up crucified. He did not adhere to all of the Torah laws He was supposed to. For an example, He touched unclean lepers, etc. He healed the sick on the Sabbath, causing scandal. He was not Torah observant in certain matters that would ultimately pertain to and be revealed in the New Covenant.
No one individual Jew can observe all of Torah.
The reason why the Hellenized, corrupt, establishment Jews (from the tribe of Levi when it should have been the tribe of Judah) in the civil and religious leadership positions is because he expected them to observe Torah in both letter and spirit.
In the first Temple period the spirit of the Torah was followed. During the second the letter of it was followed. Jesus was not only trying to get the establishment to follow it in a balanced fashion, but the rest of the Jewish population as well.
